Subject: oops when using ide-cd with 2.5.45 and cdrecord

Hi,
I'm a using the last cdrecord version (1.11a39) when this oops occurs. I can't 
sync
my disks with alt-sys-request because we are in interrupt :(
Kernel is build with gcc ersion 2.95.4 20011002 (Debian prerelease). I've two
scsi drives, one scsi cdr and a new one in ide (cdrw). See the dmesg boot below.
